Why compress your images?
Faster Page Loads
Smaller images load 2–5× faster. A 1 MB photo compressed to 200 KB cuts load time dramatically, reducing bounce rates.
Better SEO Score
Google PageSpeed Insights rewards compressed images. Faster sites rank higher in search results and attract more organic traffic.
Save Storage & Bandwidth
Reduce hosting costs by up to 80 %. Compressed images use less server storage and less CDN bandwidth — savings that scale as you grow.

Frequently Asked Questions
What quality setting should I use?
80 % is the sweet spot for web use — visually lossless but 60–80 % smaller. For print, use 90 %+. For email or social, 70 % is fine.
Does compression permanently reduce quality?
JPEG/WebP compression is lossy — quality is reduced slightly. At 80 %+, the difference is invisible to the human eye. PNG compression is lossless.
Which format gives the best compression?
WebP delivers 25–35 % better compression than JPEG at the same quality. Use WebP for web, JPEG for maximum compatibility, PNG for transparency.
Is my data safe?
